[Samba] Removing Printer Driver on Samba 2.2.5/6pre2 using rpcclient

Hi All.
Can anyone give me a hand here?
I'm trying to remove some printer drivers from my samba server running on 
FreeBSD 4.6 using rpcclient.
'enumdrivers' shows:

rpcclient $> enumdrivers

[Windows 4.0]
Printer Driver Info 1:
         Driver Name: [hp deskjet 930c series]


[Windows NT x86]
Printer Driver Info 1:
         Driver Name: [HP DeskJet 930C Series]

Printer Driver Info 1:
         Driver Name: [AGFA-AccuSet v52.3]

rpcclient $>

But when i try to delete a driver it gives me an error:

rpcclient $> deldriver "AGFA-AccuSet v52.3"
Failed to remove driver AGFA-AccuSet v52.3 for arch [Windows 4.0] - error 
0x705!

Thanks in advance,
